PBD-GF-2.0 | Biodegradable microparticles, no surface modification, green fluorescence, 2 um diameter

These 2 µm diameter green fluorescence-emitting microparticles are manufactured from polylactide*, a biodegradable, thermoplastic, aliphatic polyester derived from renewable resources such as corn starch or sugarcane. Recent research has shown promise in the use of these microparticles for drug transport and delivery and for enhancing the immune response when combined with antigen. 

These biodegrable microparticles have no surface modification and are stained with the green fluorescent dye Rhodamine Green. They are stable at neutral pH for at least three months and degradation can be triggered by exposing the particles to a basic or acidic pH or by enzymatic hydrolysis.

More Information

*Polylactide is also known as poly(D,L-lactic acid) or polylactic acid
